Hydrochloric and sulphuric acids can both be stored in glass bottles, but hydroflouric acid, which is the acid used for industrial etching cannot. It is stored in plastic containers (this I do remember from HS chem). This is the stuff that will eat you up if you get a drop on you. You can actually lose fingers, your hand or your life if you mishandle this stuff...nasty, nasty, nasty.

When mixed in the right combination, watch out.

(I hope I remember right that it is hydrochloric and sulphuric, not hydrofluoric and sulphuric. It goes back to nearly the Greek period I believe, and I am not sure if hydrofluoric was available then. It was stored in hardened rubber bottles, something like the old bowling ball material.)

Either of these chemicals in 6 molar solution can eat through almost anything, skin and bone are as tough as air for it to go through.

Together they can get glass also. The cream's formula I do not know, but if it eats through glass it can easily eat through you.

You can always tell when someone has been using the acid to etch. they always complain that the ends and edges of thier fingers are pealing. I will take blasting as a first,always wearing a respirator.
